[ECOS] eCos configuration question (was Re: [ECOS] General Q ...)

[John Mills <johnmills@speakeasy.net>]

Leaving aside my responses to Andrew cut in below:

 1. How should I set or clear this switch in my *.ecc files? I don't
recognize the entry in 'configtool'. Should I edit the *.ecc and 
regenerate the tree? Edit the affected 'hal.h'?

 2. In general, is there a listing in eCos or RedBoot docs about these 
[fairly obscure] switches?

Thanks for any guidance.

  If it was a clear decision, the reasons are lost in the mists of time!

  Yes:
  ../trapeze/ECOSBUILD/dist/install/include/pkgconf/hal.h:
    #define CYGSEM_HAL_VIRTUAL_VECTOR_INIT_WHOLE_TABLE 1

  Not of RedBoot. Our eCos app is expanded into RAM for execution, but 
  RedBoot lives in FLASH.

  Apparently not, if I 'grep'ed right.
